Ha! Yeah you insulated the user entirely from the menu system that PPD employed. You ensure that you set the printer to a "None" or "Raw" color mode that had been profiled (either custom or by manufacturer or batch for that model), prematched everything in the proofing RIP, and sent /DeviceCMYK + and off switch to the printer. The end user never saw the clusterf*ck.com PPD from the manufacturer.

That's what a good proofing RIP does. It hides the manufacturer's convoluted options. If it didn't, the user would touch one button and the behavior of the printer would conflict with the expectations/assumptions of the proofing system and they'd get junk.
